Abstract
A kind of new technology type as city central cooling, it is characterized in that carrying out municipal central cooling using steam power plant's steam exhaust as energy source and power, pipe network of the steam exhaust through being laid with along urban road, approach respectively needs the user of cooling supply, after air-conditioner set is converted to cooling capacity for users to use, while in winter it can heat again, steam exhaust is converted into condensed water after finishing function, pipeline along another laying flows back to heat and power plant, uses for Thermal Power Enterprises.This novel central cooling type is greatly improved resource, the synthesis service efficiency of the energy, has very positive meaning to energy-saving and emission-reduction, ecological, environmental protective, and produce good economic results in society.
Description
Technical field
The invention belongs to municipal central cooling engineering fields, as the new type in existing all types of municipal central coolings.
Background technique
City central cooling is developed so far always not as many cities central heating one in winter of Northern Part of China
Sample, the organized of the system of architectonical grow up.The steam that some north cities are also provided in summer with Thermal Corp
Freezed for users such as office building, megastore, hospitals by air-conditioner set as power, conditional Shelter in South China Cities also has
Cooling capacity is provided in summer for resident's unit etc. by modes such as river, large reservoir, lake water resource heat pumps, it is whole in fact in the summer
The municipal central cooling field in season, more open, random, no generally organized progress of scale of market development.
On the other hand, all kinds of steam power plants all over the place are in winter local with steam exhaust except northern area has part power plant
It carries out outside the central heating of city, remaining most of the time and its steam exhaust of most steam power plant are all treated as burden.
Include huge energy in steam exhaust, should adequately and reasonably be used.
Summary of the invention
It is an object of the invention to adequately using the thermal energy contained in Thermal Power Enterprises steam exhaust, turn waste into wealth.In social layer
Face can be significantly reduced the consumption to energy resource, makes Thermal Power Enterprises and forms win-win situation with colod-application family, creates good
Social benefit.
Specific embodiment
To achieve the above object, the following technical solutions are proposed: in the steam power plant adjoined with city (no matter its specific fuel
Type) exhaust steam pipeline on access steam drainage pipe, while having turned in station boiler water treatment facilities or steam exhaust line end
It is melted on the pipeline of the part of condensed water and accesses thinner fluid line.
This thick one thin pipeline enters related cooling supply after doing the relevant treatments such as corrosion-resistant thermal insulation, in Front road pavement
Region converts cooling capacity for the thermal energy of steam in the air-conditioner set that each zonule for needing cooling supply is adapted to, then through being mounted on cell
The cooling equipment system in domain is to cold unit or resident's cooling supply.What is passed through in thick pipe is the steam exhaust of steam power plant, stream in thin pipe
Dynamic is that the condensed water being converted to after function is finished in steam exhaust, and condensation flow telegram in reply factory electric power supply plant reuses.Such as the steam exhaust of steam power plant
Pressure is lower, can be pressurized before factory with vapour booster pump, to guarantee that system operates normally.
In this way, just a kind of new model has been started for city central cooling, especially to the South China that the summer hot time is grown again
Side area, when again winter can heat using double-standard air-conditioning equipment or heat exchange equipment.From system operation cost angle
Degree says that steam power plant converts condensed water for steam exhaust and needs to put into many expenses, and under this technology mode, just substantially not
It needs to put into and condensed water can be obtained, also because can additionally make a profit to market supply steam.And it is said from customer-side, user at this stage
Cooling in summer must electricity consumption, combustion gas, the steam specially produced or warm water.Cost or higher, and use exhaust steam of electric power plant then
Energy cost can significantly be reduced, hence it is evident that reduce the correlative charges expenditure of user.It certainly, is also to have pipe before system operation
Net laying is set, and the nonrecurring charges such as device configuration installation generate, but make big profits with a small capital.
The present invention has the following advantages that compared with existing all kinds of technical approach
1, society is reduced on a large scale to the economic cost of refrigeration requirement, the sufficiently effective waste heat that steam power plant is utilized,
Power plant can be made therefrom to make a profit again while reducing steam power plant's operating cost, user reduces phase because of the reduction of energy cost again
The spending answered.
2, in this mode, because the consumption for reducing to the energy is beneficial to energy conservation emission reduction, there is good environmental benefit.
3, while summer providing cooling capacity, in winter can also heat supply, be easy to create comfortable life, working environment.
Claims (2)
1. giving city central cooling by power of steam power plant's steam exhaust.It is typically characterized by using the steam exhaust of steam power plant as the energy as city
City's summer central cooling, and can heat in winter.
2. the claimed range of right refers to generate stream mode the power plant that generates electricity, no matter its fuel forms, also comprising from
Standby power plant.
